Abstract Superbubbles (SBs) are formed by the combined actions of stellar winds andsupernova explosions from massive stars in OB associations. These objectscontribute significantly to the hot gas component of a galaxy.s interstellarmedium (ISM), as well as affecting the structure of the ISM to large scales. Wepropose XMM-Newton observations of two SBs in the Large Magellanic Cloud, N70and N185, with indicators of recent interior SNe. From their X-ray spectra, wewill investigate (a) enhanced abundances indicating recent enrichment by SNejecta; (b) the energy budgets of the SBs, and whether those are consistent withexpected stellar-wind inputs; and (c) the required input of SNRs to these SBs toobtain the observed energies.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
